After auditioning the Envy at CanJam NYC earlier this year I had to buy it. It is spectacular - the best I have ever heard for the Susvara and I bet for others too. It sounded better than the Susvara's original amp IMO. This amp can drive anything to its max potential. Decided to sell since I no longer have time for listening sessions at home. This amp is in a like new condition. Original box and under warranty. Price includes shipping to US address. Feel free to contact me if you have any question. Thank you.
